Too technical for most readers to understand?
editThis article was tagged as being too technical for most readers to understand back in April of 2008, but it seems reasonably understandable to me. If nobody objects in the next seven days, I am going to remove the tag. If anyone thinks the tag belongs, please point out specific areas where I can improve the article to make it more understandable. Thanks! Guy Macon 04:52, 21 February 2011 (UTC)

Interesting Word Salad. Did the author just randomly pick words from a book ?
Article reads like Xebeche
Formation
The rear flank downdraft can arise owing to negative buoyancy, which can be generated by cold anomalies produced at the rear of the supercell thunderstorm by evaporative cooling of precipitation or hail melting, or injection of dry and cooler air in the cloud, and by vertical perturbation pressure gradients that can arise from, vertical gradients of vertical vorticity, stagnation of environmental flow at an updraft, and pressure perturbations due to vertical buoyancy variations (which are partially due to hydrostatic effects), respectively.[2]
Vertical pressure perturbations are generated by the buildup of pressure due to the vertical buoyancy, creating a pressure perturbation gradient. The subsiding air is generally dry and as it subsides the air warms adiabatically and can form a clearing in the cloud cover called a clear slot.[2] A clear slot can be observed to wrap around a tornado or form away from a tornado in the shape of a horseshoe. This clearing is most likely the formation of the hook echo region associated with tornado formation.[2] An RFD that originates in dry air and warms adiabatically can produce warmer observations out of the RFD at the surface. — Preceding unsigned comment added by 220.237.108.206 (talk) 08:01, 31 May 2016 (UTC)
